A PRO15X Designed for Demanding Sound Reinforcement Setups
The PRO15X fits into a "field" sound reinforcement logic: a robust passive speaker, easy to wire and position, designed for performances where system control is desired (separate amplification, choice of processing, modularity). Its format allows coverage of both small to medium-sized main PA and stage monitor use without changing equipment.
Another appreciated point for daily use: the 5-year manufacturer warranty is available after registration, which enhances the model's appeal for intensive use (service providers, rehearsal rooms, associations, mobile installations).
Who Is It For, and In What Applications?
This speaker is aimed at musicians, technicians, and service providers looking for a 15-inch passive speaker capable of delivering volume with directivity suited to the stage. As a main PA, it suits bands, DJs, and speeches when a present bass is desired without multiplying subwoofers. As a monitor, the 45-degree tilt facilitates close listening, especially for vocals, guitar, keyboards, or a drum kit on small stages.
Thanks to its 8-ohm impedance and recommended amplification, the PRO15X naturally pairs with a stereo power amplifier and a speaker processor (or an amplifier with DSP), following a classic and reliable sound reinforcement approach.
